++# SYNOPSIS
++#
++# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
++#
++# DESCRIPTION
++#
++# Check for baseline language coverage in the compiler for the specified
++# version of the C++ standard. If necessary, add switches to CXXFLAGS to
++# enable support. VERSION may be '11' (for the C++11 standard) or '14'
++# (for the C++14 standard).
++#
++# The second argument, if specified, indicates whether you insist on an
++# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
++# -std=c++11). If neither is specified, you get whatever works, with
++# preference for an extended mode.
++#
++# The third argument, if specified 'mandatory' or if left unspecified,
++# indicates that baseline support for the specified C++ standard is
++# required and that the macro should error out if no mode with that
++# support is found. If specified 'optional', then configuration proceeds
++# regardless, after defining HAVE_CXX${VERSION} if and only if a
++# supporting mode is found.
